Ariston Micro Genus 28HE Combi Boiler A01 Fault

[frankthegasman]

the problem is the recouperator and small pcb it takes about 1hour to fix if you get an ariston engineer in it is a bit tricky to change and you will need at least a 30mm gap to the right of the boiler to get it out,its a very common fault with this model blr,good luck.the small pcb is screwed to the base of the back of the main pcb compartment.you will be better off looking for your local ariston agent phone ariston they will give you a local number to you.

the A01 fault code is nearly always down to the pcb, 99% of the time in fact, its a common fault, but not common enough for ariston to be responsible for boilers out of the warantee. you can normaly check this yourself, while the tap is running check if the electrodes are still sparking even after the gas had lit, this means the pcb is not detecting the flame and trying to relight. eventualy it will lock out with a A01 code, if u reset it might work for a short time but eventualy u will get to the stage where it will no longer resart.

if your handy you can replace the pcb yourself, there is someone selling them on ebay for £85 thats a steel, its half the trade price never mind retail price!

pcb part number is 65103422 just search it on ebay!

These PCBs can be repaired if you have basic soldering skills. It is usually an EPOC capacitor (C903 on most boards) that fails by where the flame sensing wire connects £2 off eBay for a new one.
